SPRING STRUCTURE.

To all whom t may concern:

Be it known that I, GEORGE C. SHOEMAKER, a citizen of the United States, residing dat iVashington, in the District of Columbia, have invented certain new and useful I mprovements in Spring Structures, of which the following is a specification.

This invention relates to spring structure upholstering.

One object is to provide a covering for spring structures embodying such character' istics that the covering may be readily secured to spring structures without the necessity of sewing the side, facings to bottom facings. l

Another object resides in the provision. of means whereby side facings of upholstering coverings for spring structures may be secured to the spring structures without in any way altering the construction of spring structures as commonly placed on the market.

A still further object resides in the provision of an upholstering covering for spring structures for automobile or other seats or beds which may be effectively secured thereto without the necessity of altering the base frame of the spring structure and without tacking the side facings to the base frame.

With the aboveand other objects in view the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appen ed claim, it being understood that changesl may be made in the form, proportion, size and minor details without departingr from the spirit or sacrificing any of the advantages of the invention. n

In the drawings: Figure 1 is a front elevation of my invention. Fi 2 is a transverse sectional view thereo Fig. 3 isa detailed perspective view of the facing wire illustrating a portion of a side facing secured to a portion of the facing wire.

Referring now more particularly to the accompanying drawings, the reference characters 5 and 6 indicate upper and lower ed e wires of a spring structure ascommon y made and between whichvand Aconnected to which upper and lower frames in any suitable manner are springs 7. Y

other vehicle seats and for beds and the like are provided with leather or other upholstering covers and various methods have been employed to secure the coverings to the structures. In many instances the side facings 8 are secured to the top facing 9 after the manner illustratedat 10 in Fig. 2 and the lower edges of the side facing 8 have been secured to the base frame 6 in various ways but principally in automobile seats these sidil faoings 8 have their lower edges sewed to bottom facings so as to prevent upward movement of the side facings with relation to the base frame. In the present instance, without altering the form of base or lower border wire 6 now commonly used in spring structures I arrange to secure the side facing 8 to the base frame against upward movement with relation to the latter with or wit-hout the employment of a bottom facing.

I sew 4or otherwise secure to the entire lower edge or a portion at least, of the lower edge of the side facing 8 a wire 12. This wire 12 may be secured on the inside or out side of the side facing or the facing may be rolled or wrapped around the wire. In any event, I provide the wire at intervals with kinks 13 ada ted to project throu h openings in the tu e or roll portion 11 o the side facing, if the wire 12 be Sewed into the facing. 'lhese kinks 13 form projections which .may be disposed at any desired angle with relation to the side facing 8 but which preferably would, prior to connecting the covering to the frame, extend out at an angle to the facing 8.

In accordance With my present invention the top facing 9 together with its dependin side facing 8 is drawn over the structure and the facing wire 12 brought preferably directly over the base'. The projections 13 are then preferablybent by means of any suitable tool (not shown), or in any other' suitable manner, around the base 6, as shown particularly in, Fig. 2, when there is formed a firm connection between the lower edge of the side facing 8 and the base 6, which will prevent up'ward movement ofthe side facing 8 with relation to the structure. By virtue of these projections 13 being extended around the lower surface of the base, the spring structure rests upon thebase frame and these projections, if not solely upon the latter, upon which projections the entire structure may rest depending upon the charac ter 'of material used for ythe Base frame,

What isl-claimed is':-

A spring l:structure mcluding in combina- `springs.

tion a framefs'prings mounted on the frame,

a cover .for the Astructure includin ,a'fside facing, a Wire inclosed in the side aci'ng at the lower 'edge-thereof and bentl between its ends to `provideproections which extend laterally outwardly vt rough the facing-and'- whichtare bendqble downwardly around lthe frame to secure and hold the'lower ed e of L the side facing on the upper edge o the frame against the upward tension of the In testimony whereof I affix my signature in presence of two witnesses.
